Well well well, I know that I'm asking a very very stupid question but I have to ask because I'm really don't know. I've read a lot of tutorials about game programming, but I don't know what is offset? Sorry but can anyone explain for me? What is a offset ? Is it difference to X,Y coord?

It could be anything really, it depends on the context

I mean the "offset" in game programming, map scrolling

An offset is the difference detween a point and another reference point.

If we say that the top left hand corner of the screen is offset by 100,100 from the top left hand corner of a map it means that the top left corner of the screen will display the information at position 100,100 of the map.

Of in otherwords

123456789
1AAAAAAAAA
2AAABAAAAA
3AAAAAAAAA

The B in the disagram is offset by X=4; Y=3 within the image.

Does that help?
